   "description": "Height of the top of canopy above bare earth (Canopy Height Model; CHM);\ndata are mosaicked over the AOP footprint onto a spatially uniform grid at 1\nm spatial resolution. The CHM is generated by creating a continuous surface\nof canopy height estimates across the entire spatial domain of the LiDAR\nsurvey, derived from the LiDAR point cloud. The point cloud is separated\ninto classes representing the ground and vegetation returns.  The ground\nclassified points allow for calculation of a height normalized point cloud\nto provide a relative estimate of vegetation elevation. A surface is then\ngenerated using the height normalized vegetation points to produce the\nCHM. Any canopy heights less than 2m are set to zero for data collected with\nthe Optech Gemini LiDAR sensors, and less than 2/3m for the Riegl and Optech\nGalaxy sensors.\n\nSee [NEON Data Product DP3.30015.001](\nhttps://data.neonscience.org/data-products/DP3.30015.001) for\nmore details.\n\nDocumentation: [NEON DP3.30015.001 Quick StartGuide](\nhttps://data.neonscience.org/api/v0/documents/quick-start-guides/NEON.QSG.DP3.30015.001v1?inline=true&fallback=html)\n",
